Adolescent Opioid Misuse Attributable to Adverse Childhood Experiences.

Objectives To estimate the proportion of opioid misuse attributable to adverse childhood experiences (ACEs) among adolescents. Study design A cross-sectional survey was administered to 10,546 7th‒12th grade students in northeastern Ohio in Spring 2018. Study measures included self-reported lifetime exposure to 10 ACEs and past 30 day use of nonmedical prescription opioid or heroin. Using generalized estimating equations, we evaluated associations between recent opioid misuse, individual ACEs, and cumulative number of ACEs. We calculated population attributable fractions (PAF) to determine the proportion of adolescents’ recent opioid misuse attributable to ACEs. Results Nearly one in 50 adolescents reported opioid misuse within 30 days (1.9%); ∼60% of youth experienced ≥1 ACE; 10.2% experienced ≥5 ACEs. Cumulative ACE exposure demonstrated a significant graded relationship with opioid misuse. Compared with youth with zero ACEs, youth with 1 ACE (adjusted odds ratio [AOR]: 1.9, 95% confidence interval [CI]: 0.9‒3.9), 2 ACEs (AOR: 3.8, CI: 1.9‒7.9), 3 ACEs (AOR: 3.7, CI: 2.2‒6.5), 4 ACEs (AOR: 5.8, CI: 3.1‒11.2), and ≥5 ACEs (AOR: 15.3, CI: 8.8‒26.6) had higher odds of recent opioid misuse. The population attributable fraction of recent opioid misuse associated with experiencing ≥1 ACE was 71.6% (CI: 59.8–83.5). Conclusions There was a significant graded relationship between number of ACEs and recent opioid misuse among adolescents. Over 70% of recent adolescent opioid misuse in our study population was attributable to ACEs. Efforts to decrease opioid misuse could include programmatic, policy, and clinical practice interventions to prevent and mitigate the negative effects of ACEs.
